MATLAB: How to Access a Variable’s Value in a Nested Function

Question

How Can I see the value of variable g in Command window and Workspace?

function parentfcn(b)
a = b+1
    function childfcn
        g = a+1 
    end
end

Answer 1

The nested workspace stops existing as soon as parentfcn returns.

See however,

function r = parentfcn(b)
a = b+1
childfcn();
r = @childfcn;
    function childfcn
        g = a+1 
    end
end

together with

bbb = parentfcn(7)
s = functions(bbb)
s.workspace{1}

Notice that even though you called childfcn, that the workspace of childfcn does not include the local variable g: the workspace retrieved only includes the objects that the child shares with the parent. g stops existing as soon as childfcn returns.
